Ok I figured out how to do this.
  1. Modifiy /etc/initramfs-tools/module file and append i2c-dev line.
  2. Modify /etc/initramfs-tools/update-initramfs.conf file and change the value from "update_initramfs=yes" to "update_initramfs=all"
  3. Run update-initramfs -u
Afterwards I can confirm the /dev/i2c-* devices appear in initramfs stage.
